When Oscar Grant was killed by police at a Bay Area Rapid Transit (BART) station, the case sparked national outrage. Grant was unarmed and already being detained. Officers went to handcuff Grant, who struggled in protest, and was shot one time in the back by an office who alleged that he confused his gun for his taser. Grant was the 22-year-old father of one. The officer who took his life served 146 days in jail.
